1-1. DESCRIPTION
1-2. The Hewlett-Packard Model 5340A Frequency Counter measures frequencies from 10 Hz to
18 GHz. Sensitivity is -30dBm (7.07 mV) from 10 Hz to 500 MHz, -35dBm (3.98 mV) from 500
measurements from 10 Hz to 250 MHz and uses a n automatic transfer oscillator technique for
frequencies above 250 MHz. Features include
range, excellent AM and FM characteristics, eight-digit display, auto-amplitude discrimination,
variable resolution from 1 Hz to
1-3. Electrical and mechanical specifications are listed in Table 1-3.

INSTRUMENT IDENTIFICATION
1-5. Hewlett-Packard instruments have a 2-section, 10-character serial number (OOOOAOOOOO),
located on the rear panel. The 4-digit serial prefix identifies instrument changes. The 5-digit
number
the serial number of each instrument. If the serial prefix of your instrument differs
is
from that listed on the title page of this manual, there are differences between this manual and
your instrument.
1-6. For lower serial prefixes it will be necessary to backdate this manual to conform with your
instrument. Refer to Section VII for a listing of the changes needed.
1-7.
For higher serial prefix 5340A's, changes were made after this manual was published and
it will be necessary to change this manual to conform with your instrument. A manual change
sheet is included with this manual.

APPLICATIONS
1-8.
1-9. Since one input connector accepts all signals from 10 Hz to 18 GHz, the 5340A
adaptable to automatic systems and high speed production testing.
extremely useful in microwave measurements where signal levels are typically below the
sensitivity of most counters.
functions can be remotely programmed. In addition, the remote programming option allows for
digital outputing and programming of the octave ranges of the internal phase lock loops. Octave
range selection allows for measurements in a single frequency band to reduce the acquisition
time to typically less than 25 milliseconds. Other options include rear panel input connectors
Option 002, and high-stability time base Option 001.
OPTIONS
1-11. The 5340A can be ordered with the following options: Option 001, high-stability time base;
Option 002, rear panel input connectors; and Option 011 remote programming and digital output.
Table 1-3 lists the specifications for the options; Section VII describes field installation and gives
a n overall description of each'poption. Section I1 covers programming for Option 011.
